How’s it going? I hope that grandpa is well now. I was sorry to hear that he had a    21  last week. I hope you are in    22  health.

Things are fine here. I finished my end-of-year  23  last week, and got my report card today. I always    24  nervous when I see the envelope   25  school in the mail, but luckily I did OK this time. I   26  a really hard time with science this semester , and I wasn’t surprised to find that my    27  report was from my science teacher. She said I was lazy, which isn’t true .It’s just that I find   28  really difficult. Another disappointing result was in history. My history teacher said I could do better. The good news is that  29  math teacher said I was hard-working. And my Spanish teacher said my listening was good. Well, that’s about all the news I have for now. Mom and Dad    30  their love.

Love,

Alan
